About Gregorian Years
The Gregorian year = exactly 365.2425 days = 31,556,952 s (mean over the 400-year cycle with 97 leap years). The Julian calendar (45 BCE) used 365.25 days; Gregorian reform (1582) dropped 10 days and amended the centennial rule. Britain adopted it in 1752; Greece in 1923. Carbon-14 dates are reported in 'years BP' (before 1950 CE). 1 yr = 365.2425 d = 8,765.82 h = 31,556,952 s.
About Yoctoseconds
A yoctosecond (ys) = 10⁻²⁴ s - the smallest named SI prefix time unit. Light travels ~0.3 fm in 1 ys, about one-tenth the proton charge radius. Strong-force quark binding operates on ~1 ys timescales; W and Z boson lifetimes are ~260-290 ys. Lead-lead collisions at the LHC produce quark-gluon plasma that thermalises within a few ys. These timescales are inferred from decay widths via ΔE × Δt ≥ ℏ. 1 ys = 10⁻²⁴ s.
